Mueller Streamline DWV45STLFTGC112 45 Degree Elbow

Product Description

The MUELLER STREAMLINE DWV45STLFTGC112 is a wrot copper 45-degree elbow fitting designed for drain, waste, and vent (DWV) piping systems. It connects copper pipe using a cup-by-cup (C x C) socket configuration, allowing a 45-degree change in direction within a gravity-flow drain or vent line. Wrot copper construction means the fitting is formed from wrought copper stock, giving it consistent wall thickness and reliable solder joints. Licensed plumbers install this type of fitting when routing DWV lines around framing or structural obstructions. The 1-1/2-inch size is standard for branch drains, trap arms, and vent lines in residential and light commercial work.

This elbow is used in DWV copper piping systems in residential and light commercial construction and renovation. Typical applications include lavatory drain lines, trap-to-drain connections, and vent stack branches where a 45-degree offset is needed. The C x C end configuration requires standard copper pipe preparation — cutting, deburring, cleaning, and flux application — before sweat soldering with lead-free solder per applicable plumbing codes.

Key Features

• Wrot copper construction provides consistent wall thickness and strong, leak-resistant solder joints
• 45-degree elbow angle allows gradual directional changes suited to DWV gravity-flow drainage
• Cup-by-cup (C x C) socket ends accept standard 1-1/2-inch copper pipe on both sides
• Compatible with lead-free solder for potable-safe and code-compliant installations
• Sized at 1-1/2 inches, a common dimension for lavatory drains, trap arms, and vent branches

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2-inch copper DWV piping systems using standard C x C socket connections.

Installation Notes

Installation is performed by a licensed plumber following local plumbing codes and IPC or UPC requirements as adopted in the jurisdiction. Shut off water supply and ensure the drain line is empty and dry before soldering. Clean both the pipe ends and socket interiors with emery cloth, apply lead-free flux, and sweat-solder with lead-free solder. Do not apply flame directly to a wet or pressurized line.
